There is a Cold-SideProportional Damper installed between the First Desorption-Treated AirPipeline and the First Cold-Side Transporting Pipeline, or it isinstalled on the First Desorption-Treated Air Pipeline. When the VOCsconcentration becomes thicker, the Cold-Side Proportional Damper canregulate the airflow to adjust the heat-recovery amount orconcentration. When treating the organic waste air, it can prevent theThermal Oxidizer (TO) from being overheated due to high oxidizertemperature, and can protect it from Thermal Oxidizer shut-down andincrease the overall practicality.
